Title: Smoke detector of photoelectronic type
Inventor: HONMA HIROSHI
IPC: G01N21/59
Filed: 1979-08-24
Abstract: PURPOSE: To ensure to compensate the change in the amount of light received due to the dirt of optical system, by providing the memory circuit always holding the initial value of the photo reception signal.  
     CONSTITUTION: The output of the 1st memory circuit 8 always holding the digital value of the photoreception signal input first is in D/A conversion 10 and fed to the comparator 12. On the other hand, the output of the 2nd memory circuit 9 which renews the digital value of photoreception signal every given period is in D/A conversion 11 and fed to the comparator 12. Further as the result of comparison, if there is a difference, the gain control circuit 18 is operated with the signal from the count circuit 17 and the gain of the variable gain amplifier 6 is increased with the specified step. Accordingly, even if the amount of incident light is attenuated due to the dirt of optical system, the photoreception signal for fire discrimination is corrected to the same level as the photoreception signal in the first state without the dirt of optical system. Thus, the change in the amount of photoreception due to the dirt of optical system can be compensated.

Title: Kerosene stove equipped with electric heater
Inventor: NAKANO KAZUHIRO
IPC: F24C11/00
Filed: 1982-06-22
Abstract: PURPOSE:To prevent the upper end of front plate from becoming overheated, by extending a reflecting plate provided at the back side face of electric heater to the vicinity of the upper end of front plate. CONSTITUTION:A kerosene stove equipped with an electric heater is adapted to utilize either a combustion cylinder or an electric heater separately or both of them simultaneously for its heating function. The upper end of reflecting plate 8 of the stove is extended to the vicinity of upper end of front plate 6, that is, to the location where the former abuts with a partition board 2. An extension 8A is defined as the upper end of front plate 6. The upper end of front plate 6 is subjected not only to a convection heat by a heater 7, but also to a radiation heat by the heater 7 and a combustion cylinder 3, and consequently is apt to get excessively heated. However, as constituted by the extension 8A of reflecting board 8, the upper end can reflect all radiation heats forwardly, and is least susceptible to the high temperature of these radiation heats. As a result, the front plate 6 can prevent its upper end from getting excessively heated and therefore provides less chance for persons to get burnt.
